Greatest Common Factor
We found the factors 58,646,873 . The biggest common factor number is the GCF number.
So the greatest common factor 58,646,873 is 1.
Lets's calculate LCM of 64,90,129
2 | 64, 90, 129 |
3 | 32, 45, 129 |
32, 15, 43 |
∴ So the LCM of the given numbers is 2 x 3 x 32 x 15 x 43 = 123840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/123840
Therefore, the GCF of Fractions 58/64,646/90,873/129 is 1/123840
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 64,90,129 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(64,90,129) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(64,90,129) x common factors =1 x 6 = 6
LCM(64,90,129) = ( 64 × 90 × 129 ) / 6
LCM(64,90,129) = 743040 / 6
LCM(64,90,129) = 123840
